Conciseness

The body is dense and operational — a signals table with exact thresholds, a decision tree, a 7-step workflow — with almost no padding or explanation of concepts Claude already knows. Small trims are possible (e.g., the rationale for 410 over 404 and the 'Stack-agnostic' scope line), so it sits just below the leanest anchor.

Actionability

For an instruction-only skill the guidance is fully executable: exact numeric thresholds ("<10/month" sessions, ">24 months" since update, "rank 11 to 30" for update candidates), a concrete ASCII decision tree, per-action signal lists, and a fully specified output format (spreadsheet columns plus a 7-part summary report). These cover the common cases copy-paste ready.

Workflow Clarity

The 7-step workflow is clearly sequenced and — critically for a batch/destructive skill — includes explicit validation: "Do redirects and deletes in batches" with "Re-crawl after each batch to confirm no broken redirect chains" and post-audit measurement at 30/60/90 days, so the destructive-operation cap is not triggered. It falls short of 5 only because there is no error-recovery loop stating what to do when the re-crawl finds broken chains, and the 'Failure patterns' section is a list of cautions rather than a recovery procedure.

Progressive Disclosure

SKILL.md is a well-sectioned overview (when to use / when not to use, framework, thresholds, workflow) with two clearly signaled, one-level-deep references at the end, each with a one-line description of its contents. Verified both files exist and contain no further nested references; the body's output-format section is a condensed preview while the full column definitions live in references/audit-template.md — an appropriate split with easy navigation.

Specificity

The description names concrete actions — "audit existing content across a site to decide what to keep, update, merge, redirect, or delete" — giving five specific decision actions. It stops short of a 5 because it omits parts of the skill's coverage (scoring each URL against metric thresholds, producing a spreadsheet/report deliverable), leaving minor gaps.

Completeness

It explicitly answers both questions: what ("audit existing content... to decide what to keep, update, merge, redirect, or delete") and when ("Use this skill whenever the user wants to audit existing content, fix content decay, resolve keyword cannibalization..."). Both are stated with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

Trigger coverage is comprehensive and natural: "content audit, content decay, content refresh, cannibalization, keyword cannibalization, prune content, delete pages, redirect old pages, content inventory, what to keep, what to update, content scorecard, evergreen refresh," plus a symptom-based trigger ("traffic is dropping site-wide"). These are phrases users would actually say, including synonyms and symptom descriptions; nothing natural is missing.

Distinctiveness Conflict Risk

The niche is clear (auditing/pruning an existing content library) with distinct triggers like "keyword cannibalization" and "content inventory." However, phrases like "redirect old pages," "content refresh," and "prioritize content updates" have minor overlap risk with sibling SEO skills (single-page optimization, migration/redirect skills) that the description does not explicitly disambiguate.
